That individual came round here trying to sell me a blurred photo of my house which lies on 1 mile final to an airfield. I wasn't interested in the photo anyway but instead asked a few questions. It quickly became obvious that he was a one man operator. He had been taking photos whilst on finals to land. He was banned from self-fly hire from that airfield some time afterwards, after he was reported breaking Rule 5 over a city. The Chief Instructor followed him next time he flew and he was seen doing the same again. He denied everything, of course.
He went on to hire from another airfield. He was involved in a fatal mid-air collision not long afterwards, again, while flying at very low level near a village on a very busy military low flying route.
Photos from aircraft are great. But for safety's sake, concentrate on looking out and just get someone else to take them for you.
